Real- Time Detection of Early Signs: From Raw Data to Clinical Inssight

HRV, the variation in time between securitiva heartbeats, is a robuct indicator of autonomic nervous system function. Lw HRV is associated with autonomic neuropathy - a considenn complication of diabetes that often precedes or accordies diabetic cardiomyopathy.
